Do not join Vistajet
I just had a terrible Vistajet experience! I was a "cabin hostess" which actually means "general dogs body".
It is a budget airline pretending to be VIP.
There is little to no CRM and everyone speaks german all the time. Management have no idea what happens onboard. There is no crew food and little for the passengers. The crew eating left-overs from passenger plates!
Duty hours and regulations seem to be flexible which is a bit concerning.
I would not recommend anyone join!
